STD or something else?
I'm a 23 year old healthy male. About a week ago, I tried having sex with my girlfriend for the first time. I didn't take any protective measure then. The very first attempt to enter into her wasn't successful, and I think I hurt myself. so, I stopped and started fingering her. I was uncircumcised before and after this incident my foreskin didn't retract. After 2 days or so, I could see inflammation around the glans penis and by now it has grown up to encircle the same like a circular ring around it. Please help.
